Defensive publication

ABSTRACT

A NEW POLYPHENYL ETHER, 1,2,4-TRIS(PHENOXY)BENZENE IS DISCLOSED WHICH POSSESSES DEFINITE ADVANTAGES SUCH AS OXIDATIVE STABILITY AND LOW MELTING POINT, MAKING IT AN EXCELLENT HIGH TEMPERATURE HEAT TRANSFER AGENT, LUBRICANT, HYDRAULIC FLUID, DIFFUSION PUMP OIL AND SPECIALTY PROCESSING FLUID. THE RATIO OF CROSS SECTION OF A MOLECULE OF 1,2,4TRIS(PHENOXY)BENZENE TO LENGTH IS RELATIVELY LOW, RESULTING IN A GOOD VISCOSITY-TEMPERATURE RELATIONSHIP. A GOOD VISCOSITY-TEMPERATURE RELATIONSHIP IS NEEDED TO PROVIDE AS CONSTANT A VISCOSITY AS POSSIBLE OVER A WIDE TEMPERATURE RANGE, THEREBY FACILITATING EASY EQUIPMENT DESIGN IN REGARD TO FLOW, LUBRICITY, ETC. THE COMPOUND MAY ALSO BE BLENDED WITH LINEAR POLYPHENYL ETHERS TO IMPROVE THE PROPERTIES THEREOF.

1968. This application Mar. 19, 1970, Ser. No. 19,536 Int. Cl. C07c 43/22 US. Cl. 260-613 No Drawing. 9 Pages Specification A new polyphenyl ether, 1,2,4-tris(phenoxy)benzene is disclosed which possesses definite advantages such as exidative stability and low melting point, making it an excellent high temperature heat transfer agent, lubricant, hydraulic fluid, diffusion pump oil and specialty processing fluid. The ratio of cross section of a molecule of 1,2,4- tris(phenoxy)benzene to length is relatively low, result ing in a good viscosity-temperature relationship. A good viscosity-temperature relationship is needed to provide as constant a viscosity as possible over a wide temperature range, thereby facilitating easy equipment design in regard to flow, lubricity, etc. The compound may also be blended with linear polyphcnyl others to improve the properties thereof.
